It is normal for new cars to grind brake pads. Reasons for new cars grinding brake pads: This occurs because the brake pads and discs of a new car have not yet been properly worn in. The issue will resolve after some driving. Note that sometimes after driving in the rain, there may be unusual noises the next morning—this is normal due to slight rust on the brake disc surface. Prolonged inactivity can also cause noises, so regular driving helps prevent wear and tear. Details to consider when choosing brake pads: Check the friction coefficient, which determines the basic braking torque of the brake pads. If it's too high, it can cause wheel lock-up, loss of control, or overheating during braking; if too low, it may result in excessively long braking distances. Consider safety—brake pads generate instant high temperatures during braking, especially during high-speed driving or emergency stops. At high temperatures, the friction coefficient may decrease. Assess comfort, including braking feel, noise, dust, smoke, and odors, as these directly reflect the friction performance.
